Nevada Rancher Cliven Bundy was taken into custody by the FBI after flying into Portland for weapons charges and charges on conspiracy to impede federal officials, which stemmed from his standoff with the BLM in 2014.

After the four remaining protesters at the Malheur Wildlife Refuge headquarters in Burns, Oregon, spent Wednesday evening on live stream while the FBI surrounded the compound, they have reportedly agreed to leave peacefully Thursday morning.

The father of two of the group’s leaders, who were taken into FBI custody on Jan. 26, was also arrested by the FBI after he flew into the Portland International Airport Wednesday night.

The Oregonian reported that Cliven Bundy, 74, was “booked into the downtown Multnomah County jail at 10:54 p.m.” on the charge of conspiring to interfere with a federal officer, which is the same charge his sons Ammon and Ryan are facing.

Cliven Bundy’s charges, which also include weapons charges, stem from a 2014 standoff with the Bureau of Land Management on his own ranch in Nevada over grazing rights, which ended after federal agents were countered by about 1,000 armed protesters.

Prior to Bundy’s arrival in Portland, the “Bundy Ranch” Facebook page posted a status Wednesday announcing that he was on his way to the Harney County Resource Center in Burns, and calling for Americans to “wake up.”

WAKE UP AMERICA! WAKE UP WE THE PEOPLE! WAKE UP PATRIOTS! WAKE UP MILITA! IT’S TIME!!!!! CLIVEN BUNDY IS HEADING TO THE HARNEY COUNTY RESOURCE CENTER IN BURNS OREGON.

Four hours after the first status was posted, that page posted an update claiming that Bundy “just landed in Portland,” and was immediately “surrounded by SWAT and DETAINED.”

The page then noted that its users were “just in contact with the final four on the ground and all is quiet.”

The four remaining occupiers at the refuge, Sean Anderson, 47, and Sandy Anderson, 48, of Riggins, Idaho, David Fry, 27, of Blanchester, Ohio, and Jeff Banta, 46, of Elko, Nevada, all face charges of “conspiracy to impede federal officials.”

The remaining four said they would turn themselves in Thursday morning, after FBI agents surrounded the compound Wednesday night. The tense standoff was broadcast over live stream.

As of 8:40 p.m. PST, the FBI stated that they would not make any moves, and would wait for Rev. Franklin Graham and Nevada State Assemblywoman Michelle Fiore to negotiate the protestors’ surrender at 8 a.m. PST.
